Tactile Switches Replacement

Repair Instructions

The tactile switches used in the SARK-110 are SMD
components, which in case of failure they can be easily removed from the main board using a hot
air gun. If this tool is not available, it will convenient breaking the contact pads using a cutter or
a Dremel tool, being careful not to pull the pads off the board. Then
desolder the leads and pads with an iron and clean them with the iron
and desoldering braid. Finally put the connector in place and carefully
solder the four contact pads using a thin-tipped
iron.
